Use the pictures below to answer each question. The fractal below is created to model a tree. Original Iteration 1 Iteration 2Iteration 3a). In complete sentences, describe how this fractal tree is constructed. Be very detailedby giving each step and specify the lengthof a branch. b). Assume the length of each branch is half of the length of the previous branch (measured in feet). Complete the table below. Note that Iteration is the general formula used to count the number of branches and to measure the length of a branch in the thpicture.
